METALLIC RAILWAY-TIE.

SE'ECI'FICATION vforming part of Letters Patent No. 710,172, dated September 30, 1902. Application filed March 8.1902. Serial No. 97,338. (No model.)

To @ZZ 1.071,0771, t 77mm/ concern;

Be it known that I, HENRY WAVERY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Metallic Railway-Ties, of which the following is a full, clear, and eX- act description, reference being had to the accom panying drawings.

This invention is an improvement in steel railroad-ties of the type shown in Patent No. 525,927, granted September 1I, 1894, to E. L. Taylor. The tie shown in such patent consists, briefly, of a pair of slotted foot-plates, adapted to stand beneath and support the rails, and a T-shaped ltie-beam extending through such foot-plates in the slots thereof and having its upwardly-extending web cut out to make a hook engaging with the outer flange of the rail, there being hooks on the foot-plates engaging with the inner flange. Such a metal tie relies solely on the ballast to. keep the foot-plates from working inward. I have discovered that if the Vtie-beam instead of being a rolled solid T-iron be made of a plate doubled on itself and flanged outwardly the spring of the metalengaging the sides of the slot in the footfplates materially assists in preventing the plates working inward. Moreover, my sheet-metal beam affords a better support than the solid beam. It may be stamped out instead of being rolled, wherefore it is much cheaper, and the hook at the upper edge of the web being formed of two thicknesses of metal is much stronger than the hook formed by cutting out the solid T-beant. Moreover, the hook in the upper edge of the webs of'my beam may be very conveniently made by punching a bipennated hole in the plate before it is bent, which is a very simple and inexpensive operation.

My invention consists, therefore, of a metal railroad-tie having the slotted foot-plates combined with a' beam made of sheet metal bent on itself and flanged outwardly. This is more fully hereinafter-described, the particular characteristics of my invention being pointed out in the claims.

The drawings clearly show the invention,

plete, showing the rails in place of the rails Fig. 2 is aplan of the tie with one in place and the other removed. Fig. 3 is a perspective view of the tie-beam. Fig. 4 is an enlarged cross-section of the tie-beam. Fig. 5 is a perspective view of one of the footplates, and Fig. 6 is a plan of the blank from which the tie-beam is made.

Referring to the parts by letters, A A represent the rails, B B the foot-plates, and C the tie-beam. Each foot-plate is stamped of sheet metal and has a horizontal top member h, from which sides Zi' b2 incline downwardly. Upwardly-extending integral punched-out lugs b3 form the means of securing the inner iiange of the rail. Through the fiat top portion b is a slot b4, which alines with slots b5 of an inverted-T shape in the side portions b' b2.

The tie-beam is made from a sheetnnetal blank of the form shown in Fig. 6. This blank is cut the right size, and the holes c, having wings c', are punched out. The blank is then bent more or less closely on itself along the longitudinal medial line c2, and then the extreme edges of the blank are bent out substantially at right angles to the intermediate portion on the lines c3 o3. This produces a beam substantially of the shape shown in Figsfl toet, the bipennated opening c when thus doubled on itself providing a recess in which the foot of the rail seats, and a hook c4 for engaging the outer ange. The punching and bending of this tie-beam may be very cheaplyeffected. The result is a strong tie-beam in which the hook c4 is pare ticularly strong, in which the support c5 for the rails formed by the base of the 'recess is of double thickness, and in which the beam is given an outward spring by the pressure on the rail, causing it to bite the vfoot-plates and materially assist in preventing their working inward.

Having described my invention, I claiml. A metallic tie formed of a sheet-metal plate bent on its medial longitudinal line and flanged outwardly near its edges and haviuga recess through the bent web to receive the base of arail, said recess being undercut to provide a double hook in the outer side of the rail combined with a foot-plate having a slot for receiving said tie-beam, and lugs for receiving the other flange of the rail, substantially as described.

2. A metallic foot-plate in the form of an inverted channel having alined T shaped slots formed in its sides and a connecting-slot formed through its top, combined with a sheet-metal tie-beam formed of a plate bent on itself along the medial line and flanged outwardly near its edges, there being formed a bipennated hole through said plate at the HENRY W.
